First, I have provided passages from all over the Bible, both in this thread and the other rapture thread. It's time you started reading.
Second, Pentacost and Walvoord are both dyed in the wool dispensationalist/futurists who have influenced evangelicals to just take their word for it and not question their eschatology. What I have found is that futurists will actually question a person's salvation if a believer doesn't hold to the pre-trib, dispensationalist, futurism view. I have seen vile hatred and anger that from futurists that is equal to the January 6th rioters in Washington DC. It's irrational hatred from some because they have bought into the system. They won't even entertain the idea that futurism could be wrong.
Third, your quote from Pentacost is about post-trib so Pentacost isn't actually addressing amillenialism. He's lumping any view that isn't futurism into one bucket and then making sweeping claims as he posts the same verses I point to for the Amillennial view.
Finally, at this point, not one futurist has actually provided scripture that clearly stated that Jesus will rapture believers out of the earth before tribulation happens. Presuppositions have been proposed (God's wrath on sinners cannot happen if Christians are left), but no actual text proves a pre-trib rapture. The interesting inconsistency of a pre-trib rapture that says God's wrath on the ungodly cannot fall until Christians are removed is that, in their view, there would be at least 144,000 Israelite Christians who actually suffer during that timeframe. Yet, you're telling me God cannot bring his wrath in the ungodly if Christians remain? That's so inconsistent.
I point you to Kim Riddelbarger and his book Understanding the End Times as a book that shows you scripture from the entire Bible.

I also point you to
Robert Mounce and his commentary on Revelation which shows you John's connection to the Old Testament and the prophets.
I point you to Eric Alexander, RC Sproul, Voddie Baucham, Sinclair Ferguson, John Piper, Kevin DeYoung, and Allistair Begg, just to name a few, who are steeped in scripture and are all Amillennial in their understanding of scripture.
I leave you with a passage that John often points to in Revelation.
(Psalm 2:1-12)
Why are the nations so angry? Why do they waste their time with futile plans? The kings of the earth prepare for battle; the rulers plot together against the Lord and against his anointed one. “Let us break their chains,” they cry, “and free ourselves from slavery to God.” But the one who rules in heaven laughs. The Lord scoffs at them. Then in anger he rebukes them, terrifying them with his fierce fury. For the Lord declares, “I have placed my chosen king on the throne in Jerusalem, on my holy mountain.” The king proclaims the Lord’s decree: “The Lord said to me, ‘You are my son. Today I have become your Father. Only ask, and I will give you the nations as your inheritance, the whole earth as your possession. You will break them with an iron rod and smash them like clay pots.’” Now then, you kings, act wisely! Be warned, you rulers of the earth! Serve the Lord with reverent fear, and rejoice with trembling. Submit to God’s royal son, or he will become angry, and you will be destroyed in the midst of all your activities— for his anger flares up in an instant. But what joy for all who take refuge in him!
